Penetration testing
Web, mobile, API, network, cloud and wireless testing against current techniques, with findings mapped to owners and fix paths.
Capability 08
Purple and Red Teaming
Challenge and validate defences continuously. Penetration tests, red team operations and purple team exercises that put attackers and defenders in the same room, repeated as the estate changes.

- Defined tests, exercises or a continuous programme
- Works with
- Security operations, engineering and risk teams

- A penetration test is a snapshot. Resilience requires continuous validation
- Every red-team finding should become a detection
The challenge
A penetration test is a photograph of one day.
The estate changes the next morning: a new endpoint, a dependency upgrade, a configuration drift, a new AI integration. Findings from the annual test are fixed once and the test is filed. Prevention was checked; detection was assumed.
Resilience requires validation that keeps pace: automated testing in the pipeline, scheduled tests on production, and exercises in which the red team runs a technique, the blue team checks whether the SIEM saw it, and both fix the gap the same day.
What we deliver
Offerings.
Take one offering on its own, or combine them into a programme with a named lead and agreed exit criteria.
Red team operations
Objective-based adversary simulation across people, process and technology, under agreed rules of engagement.
Purple team exercises
Attackers and defenders together: each technique run, each detection checked, each gap closed while everyone is in the room.
Continuous validation programme
Breach and attack simulation, scheduled re-tests and pipeline testing, so the picture is current rather than annual.
Testing in the delivery lifecycle
Security testing embedded at every phase of the SDLC with our Application Security practice.
OT-safe assessment
Industrial and clinical networks assessed without probing production controllers: passive observation, offline analysis, no risk to the line.
Approach
How an engagement runs.
A named practice lead from scoping to close, with deliverables agreed before work starts.
Scope
Objectives, boundaries, rules of engagement and what success looks like, in writing.
Execute
Test or simulate, with your defenders informed to the degree the exercise requires.
Debrief
Findings with the people who own them, and the detections that did or did not fire.
Re-test
Confirm the fix, then schedule the next pass.
Outcomes
What changes for you.
Measured outcomes from real engagements will be published here once clients consent.
Findings that get fixed
Every finding with an owner, a fix path and a re-test date.
Detection gaps closed
The SIEM checked against real techniques, not assumed to work.
Resilience over time
A trend, not a snapshot, that leaders can read.
Questions
Frequently asked.
Is testing safe on production systems?
Rules of engagement define what is tested, when and how. On industrial and clinical networks we observe passively and never probe production controllers.
What are your testers' credentials?
Our testers hold Certified Red Team Analyst (CRTA), Certified Ethical Hacker (CEH) and Computer Hacking Forensic Investigator (CHFI) certifications, and Rhinexa is certified to ISO/IEC 27001:2022. Every engagement has a named lead accountable for the work.
How often should we test?
Automated checks on every release, scheduled tests at least annually and after material change, and purple exercises on a cycle that matches how fast your estate moves.
What do we receive?
A report written for two audiences: an executive summary with risk in business terms, and technical findings with reproduction steps and fix guidance.
